ALFONSO ZEVADA BALDENEBRO, OF MEXICO, MEXICO.

AIVILGANIATOR.

SPECIFICATION forming part of Letters Patent No. 649,796, dated May 15, 1900.

A Application filed September 14, 1893. Serial No. 690j941. (No modelo To all zul/'wm it 71mg/ concern,.-

Be it known that I, ALFONSO ZEVADA BAL- DENEBRO, of the city of Mexico, in the Republic of Mexico, have invented a new and Improved RotaryAmalgamator, of which thc following is a full, clear, and exact description.

My invention relates to the treatment of gold ores, and has for its object to provide an improved apparatus which will be comparatively simple in construction and efficient in operation.

The invention will be fully described hereinafter and the features of novelty point-ed ont in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is, an elevation of the rotary amalgamator, with parts in section, on the line 1 1 in Fig. 2. Fig. 2 is a plan thereof. Fig. 3 is a detail of the water-supply valve. Fig. 4 is a section on the line 7 7 of Fig. 3. Fig. 5

is a broken detail of the mechanism for adjusting the water-discharge tubes. Fig. 6 is a plan thereof. Fig. 7 is a section on the line 10 10 of Fig. 5. Fig. S is a detail of the stationary brush. Figs. 9 and 10 are sectional details of the mechanism for adjusting the water-discharge tubos, Fig. 9 showing parts in section substantially on the line 9 O of Fig. 1; and Fig. 11 is a perspective view of this adjustingmechanism and its connections with part broken away.

The rotary amalgamator comprises a rotary table A, inclined toward its peripheryand secured to the shaft B, which may be rotated by means ot' the driving-gear F, and rests upon a step-bearing K. The shaft may be provided with a funnel 15 to collect any drippings of oil or the like. Adjacent to the top of the table A is located an approximatelysemicircular channel C, tapering toward the bottom, at which it is open longitudinally and supported by means of bars 1 and 2, secured to the frame R of the amalgamator. The said bars also carry a rectangular pipe D, connected with a water-supply pipe ll. The channel C and pipes D and ll are stationary. The channel O is divided into two sections 3 and by a vertical partition 5. From the rectangular pipe D extends a series of approximately-radial pipes, such as 6, 7, and 8. From the pipe 8 branches off a pipe 9 and from the pipe 7 branch pipes 10 and 1l, adj ustable,as Willbe described hereinafter. The pipes G, 7, and 8, beyond the periphery J of the table A, are adapted to discharge into a channel or trough I, which extends around the table and dips toward the oppositely-arranged points U, at which are arranged the outlet-chutes for the material flowing oit the table A. The pipe (3 has small branch pipes 12, 13, and 14, provided with regulatingvalves N N N2 ot the construction shown in Figs. 3 and 4. According to this construction a disk 40 is mounted to rotate about an axis 41, located eccentrically in relation to thc pipe 13 and provided with a series of graduated openings 42, so arranged as to successively register with the passage of the pipe 113 when said disk 40 is turned about the axis 4l. The rotary movement of the disk is effected by means of a hand-wheelM upon a shaft 43, carrying a gear-wheel 45, which meshes into the gear-wheel 4G, forming a part of the disk 40. It will be obvious that by this means the rate of the discharge of the water may be regulated.

The table A consists of copper covered with amalgamated silver. The plate is held upon the shaft B by means of a clamping-support 1G and is further supported by means ot' braces j, which are carried by a collar 1S on the shaft B. table is strengthened by a rim M, and connection from the center to the periphery is made by means of T-beams 17.

In order to adjust the angle of the pipes 10 and 11, I employ the universal joint shown in Figs. 5to 7and 9 and 10. Upon the pipe 7 is secured a clamp consistingof two sections 21 and 31, held together by means of screw-bolts 25, having nuts 34., and screw-threaded sockets 35. The section 31 is capable of sliding up and down on the bolts 25. To the uppersection 2i is secured by screws 23 a socket 22, which receives a ball 2l, rigid with a guideframe 19. This guide-frame 19 receives loosely an arm 20, which is adapted to slide therein. In the screw-threaded sockets 35 of the bolts 25 is adapted to turn a screw-shaft 26, provided with a crank-handle 2S and with a con.-

The peripheral section of the ical or wedge-shaped projection 27, which is adapted to engage the lower section 31 of the clamp. The upper section 24 ofthe clamp is apertured to receive the screw projection 29 of a shoe 33, adapted to engage the pipe 7. The screw engages a sleeve 30, arranged Within the socket 22, and the screw is also adapted to engage endwise the ball 21, located in said socket. It ywill be understood that by turning the crank-handle 28 the sections 24 and 31 can be drawn tight upon the pipe 7 or 'freed therefrom in such away asto allow the clamp to turn upon the shaft, the ball 21 allowing the guide 19 and the bar 2O therein to turn relatively to the clamp. Furthermore, the clamp can be moved longitudinally of the pipe 7. The connection between the bar 2O and the pipe 10 or 11 is made as shown in Figs. 5, 6, and 7V-that is, the bar 2O has connected to it a screw-eye 32, which receives the pipe4 11, as shown.

As, shown in Fig. 1, the clamps 24 31, with the guide 19 connected to the clamp member 24 by the universal joint, as described, may be attached to the pipe 7, with the said guide either above the pipe 7 (as shown toward the center) or below the same, (as shown toward the periphery.) Fig. 9 shows the former arrangement, while the latter arrangement (or parts of it) is represented in Figs. 5, 7, 10, and 11. A handle 19a may be attached to the rod 2O to allow the same to be readily moved. I t will be obvious, however, that Fig. 9 shows exactly the same construction as the other figures, only in a diierent position or arrangement. One or the other position will be used, according to the desired distance from the branch pipe 11 to the table proper.

In addition to the parts above enumerated the rotary amalgamator comprises a brush E, mounted along one of the radii of the table A and adjustable toward and from the same, the brush being mounted to slide vertically upon a stationary guide G, also a pipe P, through which mercury may be discharged potassium cyanid.

In operation the material arriving at the feed-channel d runs into the channel C, and escaping through the bottom thereof is spread upon the table A, and owing to the rotation of the table runs down the same upon spiral lines, during which travel it is subjected to the action of streams of water delivered from the various water-nozzles and also to the action of mercury issuing from the pipe P.

` Furthermore, the amalgamated surface of the plate A will retain a very large proportion of valuable material. The potassium cyanid will dissolve some of the gold and the'solution may be treated in any approved manner.

Before the material is allowed to flow upon the table A said table is cleaned by allowing potassium cyanid to iiow over it and then amalgamating the table. The brush E is lowered each time it is desired to clean the table A during its rotation.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of the rotary amalgamated table, the stationary Water-pipe above it, a clamp embracing said pipe, a shaft journaled in bearings rigidly connected with one clamp member, a Wedge projection located upon said shaft and adapted to engage the other clamp member, a guide having a universal joint connecting it with the clamp, Va rod slidable in said guide,a branch pipe communicating with said water-pipe but movable relatively thereto, and a supporting connection between said rod and the branch pipe.

'2. The combination of the amalgamated j rotary table, the stationary Water-pipe above it, a movable branch pipe attached to said water-pipe, a clamp secured to the Waterpipe, aguide connected with said clamp bya universal joint, and a rod having a supporting connection with the branch pipe, and arranged to slide in said guide.
